Abstract

Abstract The invention relates to a soil cultivating machine comprising at least one roller (11) to work the soil as well as scraper members (15) which include a plurality of parts that are interconnected otherwise than through welding. A scraper member (15) includes an arm (25) consisting of two parts (27) arranged alongside each other and mounted between the legs of a U-shaped support (18), which legs are detachable relative to each other. The scraper member arm (25) is arranged slidably between the legs of the U-shaped support (18). The arm (25) consists of two strips (27) arranged against each other, the front side of which is provided with a curved part constituting a support for the application of a scraper element (28).
